"I'm friends with [Obama's former aide] Reggie Love and I was at the White House," Munn explained. "I looked up and realized I was in the Oval Office.

"Of course, I'm texting because that's what I'm always doing. I am texting somebody and I look up and I see Obama and I look back down - it's not registering that it's him. I totally gave him the brush-off, like, 'Oh hey, what's up, Obama?'"

Munn continued: "I had to do a double-take, like, 'Oh my God, I am so sorry'. It was so embarrassing. I was like, 'I don't want you to think that I was the girl that was like uhhh'."
